Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 34189-74-7 Ethyl-13C2 iodide Iodoethane-13C2.
CATO supplies 34189-74-7 Ethyl-13C2 iodide Iodoethane-13C2 (CAS 34189-74-7), a certified reference material (molecular formula [13C]2H5I, MW 157.95 g/mol) for analytical method development and quality control.
The molecular framework of 34189-74-7 Ethyl-13C2 iodide Iodoethane-13C2 ([13C]2H5I) is characterized by iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 34189-74-7 Ethyl-13C2 iodide Iodoethane-13C2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
